Yes, the tank mount can crack and break. Most often it is because there was some stress on it....and over time the vibration caused it to crack. Sometimes it cracks the tank as well, and the owners finds the crack because the tank started dripping fuel.
Welding is the only proper repair. If the crack is only on the mount tab, it can be welded pretty easily. If the crack is under the tab and on the tank it is much harder to weld....and requires cutting the tab off, welding the tank then welding the tab back on.
Welding on motorcycle fuel tanks is not as hard as on big tanks with baffles in them - the tank takes very little time to clean and dry. Dump the fuel out...remove the cap and petcock....and let it air out for a week if the tank is clean inside. If it has varnish and rust then go to the Tech Section and read up on how to clean a rusty tank. Set the tank in the sun outdoors when possible, put an aquarium pump hose inside if you have one......let it air out until you can' t smell fuel anymore.
